sexing salmon faverolles -- can pullets have grey?

[farmergal]

When can you really tell the sexes of salmon faverolle chicks? Mine are 6 days old, and I've been watching their wing feathers really closely. Only 1 chick of the 6 doesn't have any grey or black on the feathers. (Its wingfeathers are a light, almost pinkish color.) The other six all have some grey in their feathers, ranging from light grey to almost black.

Does this mean I have 5 roos and 1 pullet?

Or can some of the pullets have a bit of grey on them too?

any pics or advice would be appreciated!

 

[what was i thinking]
